| description | The present invention relates to the use of a composition comprising: 70 to 91% by weight of at least one semi-crystalline polyamide, 5 to 25% by weight of at least one polyolefin having an epoxy, anhydride or acid function introduced by grafting or copolymerisation, 3 to 20% by weight of at least one plasticizer, 0.05 to 5% by weight of at least one stabilizer on the basis of a copper complex, and at least one catalyst, said composition being free from alkaline metal halide and oligo- or polycarbodiimide, as sealing layer in a pipe containing oil or gas, the pipe being used in the exploitation of offshore oil or gas reservoirs. |
